ACETYLENE-GAs- GENERATlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 699,828, dated May 13, 1902;

Application filed m 25, 1901.

To all whom it may concern:-

Be it known that I, Annnns EDWARD ADOLFSSON, engineer, of Sundhyberg, in the Kingdom of Sweden, have made certain new and useful Improvements in Acetylene-Gas- Generating Apparatus, of .which the following is a specification.

This invention relates to acetylene-gas-gencrating apparatus of that kind in which the carbid is fed down into water by an oscillat ing feeding vessel moved from the gasometer.

The object of the invention is a device for preventing the feeding vessel from swinging or oscillating beyond a certain limit, even if the gasometer should rise higher than usual, owing to an increase in the gas generation for a given feed.

On the accompanying drawings,Figure1isa Vertical section ofsuch an apparatus,illustrating the feeding vessel preferred to be used. Fig. 2 is a side view of the apparatus, illustrating the device forming the object of my application; and Fig. 3 is a plan view of the same. Fig. 4 is a perspective View of the feeding-plate; and Fig. 5 illustrates the position of the arm 61 at the ends of the stroke, the wheel a being removed.

In Fig. 1, a is the carbid-receptacle, I) the generator, 0 the feeding-plate, which is adapted to be oscillated on a horizontal axis at the movements of the gasometer a; by means of an arm or a wheel a. Connected to said gasometer 50 is a casing surrounding the feeding-plate and communicating with the generator by the opening g. The feeding-plate has the shape of a scoop or of a shutter provided with side walls, as illustrated in Fig. 4, the long edges of which shutter do not reach the circumference of the casing f. The said shutter or plate at its lower edge is provided with brushes 7L, bearing against the surrounding casing, and on each side of the opening leading from the carbid-receptacle there is arranged a yielding abutment t' 7t. At the sinking of the gasometer the wheel a will be turned, thus turning the feeding-plate from the position illustrated in Fig. 1, whereby the mouth of the carbid-receptacle is successively shut and the communication between the inside of the casing f and the generator opened. The brushes h and the abutment '5 Serial No. 69,706. (No model.)

completely shut off the communication between the generator and the inside of the casing f when the feeding-plate has the posi tion shown in Fig. 1, and at the oscillation of the said plate its upper edge at is always in contact with one of the abutments '1: or 70, thus always keeping the direct passage between the generator and the carbid-receptacle closed.

7 The device used for operating the feedingplate 0 consists of an arm or a wheel a, mounted loosely on the shaft d of the feedingplate and connected with the gasometer, for instance, with a rope y, so as to turn when the gasome'ter falls. The wheel a is also loaded with a weight 2 or a spring, which acts to turn the wheel in the opposite direction at the rising of the generator. The said wheel a has a laterally-projecting pin 0, in the path of which, during the movement of the wheel, is a double lever d, curved on the outside and pivoted on an arm e, projecting from the shaft d, and said lever d is provided at its ends with axially-projecting pins f f", one or both of which, according to the position of the lever, bear on the circumference of a stationary curved guide 9, which is bent inwardly or provided with inwardly-pointing slots h h at the points corresponding to the extreme positions of the feeding-plate. In the position of rest the pinf orf is situated in either of the slots h hfor instance, the pin f in the left slot h in Fig. 2; but when the gasometer descends and turns the wheel a the pin a of the latter slides into a recess in the back of arm cl in its path, consequently lifting said arm and causing the pinf to gradually slide out of the slot h and the pin f to be forced inward and both to follow along the curved circumference of the guide until the forward pin snaps into the sloth at the other end of the guide. During this movement the shaft 01 of the feeding-plate is likewise turned under the influence of the arm d, supported by the arm 5; but as soon as the pin f has entered the slot h or arrived beneath the end of the guide g any further motion of the gasometer-t'. e. any continued rotation of wheel a will only have for result that the pin f" slides farther into said slot and that the lever cl is turned, not raised or shifted, the arm 6 therefore neither being turned and the motion of shaft 61 and the feeding-plate conse-. quently ceasing in spite of the continued movement of the gasometer. When the gasometer is subsequently raised once more and the wheel a thus turned back under the action of a spring or the weight 2, the arm (31 is first turned so that the pin f begins to slide out of the slot 71, whereupon the arm 01 is lifted and turned, said lifting motion being transmitted through theiarm e to the shaft 03 and the feeding-plate, which now begins to be returned into its original position. In the continued motion the two pins f f find a bearing against the curved surface of the guide, and finally the pin f again slides into the slot 71/ beneath the left end of the guide.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is In an acetylene-gas-generating apparatus, the combination with the generating-chamher and gasometer, of a carbid-feeding ves= sel, a feeding-plate therein, a shaft supporting the said plate, an arm or wheel on said shaft, a pin carried by said arm or wheel, a double lever secured to the shaft of the feedingvvessel and having a curved outer back part on which said pin acts, pins carried by the branches of said double lever, a stationary guide on which one of the pins always bears when the lever is moved by the pin on the arm or Wheel, said guide, at parts corresponding to the extreme positions of the feeding vessel, having slots or edges extending radiallyinward permitting further movement of the wheel without turning of the feeding vessel, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
